Functions

void lv_refr_now(lv_display_t *disp)

Redraw the invalidated areas now. Normally the redrawing is periodically executed in lv_timer_handler but a long blocking process can prevent the call of lv_timer_handler. In this case if the GUI is updated in the process (e.g. progress bar) this function can be called when the screen should be updated.

参数:

disp -- pointer to display to refresh. NULL to refresh all displays.

void lv_obj_redraw(lv_layer_t *layer, lv_obj_t *obj)

Redrawn on object and all its children using the passed draw context

参数:

• layer -- pointer to a layer where to draw.

• obj -- the start object from the redraw should start
